Description

[0001] technical field

[0002] The invention relates to a water-based elastic feel paint and a preparation method thereof, belonging to the technical field of paints.

[0003] Background technique

[0004] Under the pressure of smog, the National People's Congress revised the Environmental Protection Law for the first time in 25 years. The revision of the "Environmental Protection Law" was passed, which increased the punishment of large polluters. The amendment clearly stipulates that polluting enterprises can be punished according to the original The amount is continuously punished on a daily basis. Especially in the electronics industry, the environmental protection requirements for the surface coating of products are more stringent.

[0005] Nowadays, the requirements for the appearance effect of daily necessities are getting higher and higher, such as aluminum powder effect, crack effect, elastic feel effect, etc., especially for some parts that are often touched by ...
